Abstract
650,305. Controlling aircraft. NORTH AMERICAN AVIATION, Inc. April 10, 1947, No. 9563. Convention date, April 22, 1946. [Class 4] [Also in Group XXIX] In order to reduce the effects of air gusts on an aircraft, a device sensitive to vertical airflow is mounted on the wing and arranged to operate a device for effecting direct variation of wing lift to compensate for the effect of such vertical airflow. As shown, a vane 27 mounted ahead of the wing 22 is arranged to operate trailing edge flaps 18, 181 on the ailerons and lift flaps 19, 20 respectively, through the agency of a relay valve 16 and fluid pressure servomotor 17 (see Group XXIX), the flaps being raised to reduce the lift when an upward gust is encountered, and conversely. The vane may be carried between arms projecting from the leading edge of the wing in the case of a single-engined aircraft, or at the nose of the fuselage of a twin-engined machine. The rod 37 of the servomotor 17 actuates the flaps 18, 18<SP>1</SP> through linkages 38, 39, 39<SP>1</SP>, 41, 411, 42, and a trim tab 31 on the vane 27 is operated simultaneously with the elevators 73 through a linkage 71, 72, 74, 75. A pitot tube may be used in conjunction with the vane 27 to vary the rate of response of the servomechanism in accordance with the speed of the aircraft. Instead of employing flaps to vary the lift characteristics of the wing, spoilers or boundary layer control devices may be used.
